Screwed Check Valve

A Screwed Check Valve is a flow control device that permits fluid to pass through in a single direction while preventing any reverse flow. It operates with a simple mechanism involving a movable disc or flap that opens under forward flow pressure and closes tightly against the valve seat to block backflow. This type of valve is commonly used in plumbing and industrial systems to safeguard against unwanted fluid reversal and is distinguished by its ease of installation due to the screwed ends that allow for straightforward connection to pipes.
